U.S. Army Corps of Engineers civil works controversies

Last updated

The United States Army Corps of Engineers is involved with a wide spectrum of public works projects: environmental protection, water supply, recreation, flood damage and reduction, beach nourishment, homeland security, military construction, and support to other Governmental agencies. Through 19 Flood Control Acts since 1917, Congress has authorized the Corps of Engineers to be involved with flood protection and damage reduction in almost every state of the union.

Contents

Corps of Engineers' projects are either authorized specifically by Congress or as part of a Congressionally authorized category of projects. Projects are authorized and built in all fifty states, [1] Local citizen, special interest, and political groups can lobby Congress for authorization and appropriations for specific projects in their area. In contrast, locals have also opposed corps projects or parts of projects. [2]

Many of the Corps of Engineers' civil works projects have been characterized as being riddled with patronage (see pork barrel) or a waste of money and resources (see boondoggle (project)), such as the New Madrid Floodway Project [3] and the New Orleans flood protection. [4] Projects have allegedly been justified based on flawed or manipulated analyses during the planning phase. Some projects are said to have created profound detrimental environmental effects and/or provided questionable economic benefit such as the Mississippi River Gulf Outlet in southeast Louisiana. [5] Faulty design and substandard construction have been cited in the failure of levees in the wake of Hurricane Katrina. [6] Reforming the Corps' way of doing business has been championed by U.S. Senators Russ Feingold and John McCain. [7] Holding the corps accountable has been proposed by the group Levees.org led by Sandy Rosenthal. [8]

One of the difficulties of making changes, however, is the political process itself. [9] [10] Depending on the point of view of any debate on these projects, they may or may not be considered sound from an engineering standpoint (see below). Whether or not USACE planners and engineers actually do the best they can with what they are directed to do is part of the controversy.

Levee Failures in New Orleans During Hurricane Katrina

Description of Failures

On 29 August 2005, Hurricane Katrina passed to the east of New Orleans, the Corps's flood protection failed catastrophically with levee breaches in over 50 places. The levee failures caused massive flooding in New Orleans with associated property loss and drownings. When Katrina arrived, the hurricane protection authorized was between 60 and 90% complete; the projected date of completion was estimated to be 2015.

Authorization in the Flood Control Act of 1965

The Flood Control Act of 1965 (FCA 1965), enacted after Hurricane Betsy flooded large sections of New Orleans, mandated the US Army Corps of Engineers as the Federal agency responsible for levee design and construction. Among other projects and studies, FCA 1965 authorized the Lake Pontchartrain and Vicinity, Louisiana Hurricane Protection Project. The project was to construct a series of control structures, concrete floodwalls, and levees to provide hurricane protection to areas around Lake Pontchartrain. Although federally authorized, it was a joint federal, state, and local effort. [2] The state and local effort was handled by the Orleans Levee Board which provided operational control and maintenance of the levees after the corps turned completed structures over to it.

Investigations of the levee failures

In October 2005, Lt. Gen. Carl Strock, Chief of Engineers and the Commander of the Corps of Engineers, established the Interagency Performance Evaluation Task Force (IPET) to "provide credible and objective scientific and engineering answers to fundamental questions about the performance of the hurricane protection and flood damage reduction system in the New Orleans metropolitan area. [11] IPET membership consisted of multiple employees of the U.S. Army Corps of Engineers, past and present, as well as individuals from academia, other states, water experts, and other Federal agencies.

An October 2005, Washington Post article reported that "...local officials often resisted proposals to protect their communities from storms because they did not want to pay their share of federal projects. [12] However, this claim was refuted in an August 2015 report published in Water Policy, the official journal of World Water Council. The authors concluded, "... we have not uncovered any information that would suggest that the members of the OLB who served on the Engineering Committee or the OLD staff engineers behaved irresponsibly or in a manner that did not place the interests of the city residents at the forefront...." [13]

In June 2006, General Strock accepted responsibility on behalf of the Corps for the failure of the flood protection, calling it "a system in name only." Faulty design specifications and incomplete or substandard construction of levee segments contributed to the failure of the flood protection. [14]

In April 2007, the American Society of Civil Engineers (ASCE) began referring to the flooding as the worst engineering catastrophe in US history. [15] On 1 June 2007, the American Society of Civil Engineers issued its External Peer Review (ERP) report, [16] the peer review of the Corps-sponsored IPET and also an accompanying press release. [17] However, the press release was criticized because it contained information that was not present in the report, included information that conflicted with the report, and minimized the Army Corps' involvement in the catastrophe. The press release stated, "Even without breaching, Hurricane Katrina’s rainfall and surge overtopping would have caused extensive and severe flooding—and the worst loss of life and property loss ever experienced in New Orleans". Meanwhile, the ERP report stated that had levees and pump stations not failed, "far less property loss would have occurred and nearly two-thirds of deaths could have been avoided".

On 9 July 2007, retired LtG Elvin "Vald" Heiberg III, stated in a letter to the New Orleans Times Picayune that people should blame him for the Katrina disaster. He says that, as Commander of the New Orleans District and later as the Commander of the Corps of Engineers in the mid 1980s, he gave in to local interests – notably, Save Our Wetlands – too easily after various legal challenges. [18] However, two law professors, Thomas McGarity and Douglas Kysar, in their article that highlighted the 'hazards of hindsight analysis,’ put the process under the microscope and concluded that the corps had decided to build what locals preferred. The corps had not been forced to do anything against its will. [19]

The IPET draft findings indicate that,

With the exception of four foundation design failures, all of the major breaches were caused by overtopping and subsequent erosion. Reduced protective elevations increased the amount of overtopping, erosion, and subsequent flooding, particularly in eastern New Orleans. The structures that ultimately breached performed as designed, providing protection until overtopping occurred and then becoming vulnerable to catastrophic breaching. The levee-floodwall designs for the 17th Street and London Avenue Outfall Canals and IHNC were inadequate. In these cases, the structures failed catastrophically prior to water reaching design elevations. A significant number of structures that were subjected to water levels beyond their design limits performed well. Typically, in the case of floodwalls, they represented more conservative design assumptions and, for levees, use of higher quality, less erodible materials. [11]

In October 2007, Dr. Ray Seed, University of California-Berkeley civil engineering Professor and ASCE member submitted an ethics complaint to the ASCE alleging that the corps with the help of the ASCE sought to minimize the corps' mistakes in the flooding, intimidate anyone who tried to intervene and delay the final results until the public's attention had turned elsewhere. [20] The corps acknowledged receiving a copy of the letter but has refused to comment until after the ASCE's Committee on Professional Conduct (CPC), led by Rich Hovey, comments on the complaint. [21] It took over a year for the ASCE to announce the results of the CPC. [22] When the results of the internal ethics investigation were announced, the ASCE panel did not file any charges of ethical misconduct against any of its staffers. They blamed their errors in their June press release on "staff level and not by review panel members." [23]

An external task force led by retired congressman Sherwood Boehlert (R, NY) also conducted an investigation. [24]

Boehlert's task force was assembled at the request of ASCE in response to Dr. Seed's ethics complaint and also a video produced by Levees.org spoofing the apparent conflict of interest. [25] The task force consisted of members from the [National Science Foundation], the [National Academy of Sciences], the [National Institute of Standards and Technology], and the [American Water Works Association]. [26]

The task force's report criticized how ASCE conducts its peer reviews and recommended improvements. Most notably throughout the document was the inadequate "consideration of real or perceived conflict of interest". The task force acknowledged that the "[P]otential conflicts of interest in ASCE's engineering review process are not unique to ASCE and can be addressed through procedures utilized by many government agencies charged with providing unbiased assessments to the public" Mr. Boehlert's task force also praised ASCE by writing, "ASCE has long been respected for its investigatory skill and expertise, and its work on assessments is held in high regard by those in the engineering profession. ... The Task Force believes ASCE remains the best option for conducting post disaster engineering assessments."

The grassroots group, Levees.Org, claimed that the IPET investigation and an expert review panel (ERP) convened by ASCE lacked credibility because of the involvement and management of the Corps of Engineers. [27] The group contended that the ERP validating the IPET process was an apparent conflict of interest because the Corps selected the ASCE, directly paid the ASCE over $2 million and awarded the panel members Outstanding Civilian Service Medals (OCSM) before their work was complete. Levees.org was not successful in convincing members of Congress to create an independent levee investigation commission.

Lawsuits Against the Corps in New Orleans

In March 2007, the City of New Orleans filed a $77 billion claim against the USACE for damages sustained from faulty levee construction and resultant flooding during Hurricane Katrina. [28] Hundreds of thousands of individual claims were also received in the New Orleans branch office of the USACE. In addition to the City of New Orleans, other claimants include Entergy New Orleans, the city's now-bankrupt electric utility, and New Orleans Sewerage and Water Board. [29]

In February 2007, the U.S. District Court ruled that the Flood Control Act of 1928 did not apply to cases involving navigational projects [30] but that the Corps may be sued over alleged defects in its Mississippi River-Gulf Outlet navigation channel.

In January 2008, the District Court ruled that even though the US Army Corps of Engineers was negligent and derelict in their duty to provide flood protection for the citizens of New Orleans, he was compelled to dismiss a class action lawsuit filed against the Corps for levee breaches after Hurricane Katrina due to FCA 1928 which protects the federal government from lawsuits over flood control projects. [31] The case was not appealed.

In November 2009, the US District Court for Eastern Louisiana held the US Army Corps of Engineers responsible for the flooding from the two east IHNC levee breaches (and dozens of others) because the federal agency failed to properly maintain the Mississippi River Gulf Outlet (MRGO). As of June 2011, the federal government has appealed the ruling.

In April 2010, scholars with the Louisiana State Office of Historic Preservation approved the text for a Historic Plaque for the 17th Street Canal. After receiving permission from city agencies and the Corps of Engineers, the flood protection group Levees.org installed the Plaque at ground zero, on New Orleans city property, in the Lakeview neighborhood.

The text of the plaque read as follows:

On August 29, 2005, a federal floodwall atop a levee on the 17th Street Canal, the largest and most important drainage canal for the city, gave way here causing flooding that killed hundreds. This breach was one of 50 ruptures in the federal Flood Protection System that occurred that day. In 2008, the US District Court placed responsibility for this floodwall's collapse squarely on the US Army Corps of Engineers; however, the agency is protected from financial liability in the Flood Control Act of 1928.

Internet Online Commenting Controversy

In December 2008, the Sandy Rosenthal leader of the group Levees.org called a New Orleans CBS affiliate television station and offered to give them an exclusive to publicize several incidences[ spelling? ] in which employees of the corps used taxpayer-funded computers to post derogatory blog comments deriding citizen activists' efforts. In response to the news story, the U.S. Army Corps of Engineers described the event as an isolated incident. [32] Three days after the incident was publicized, the Commander of the New Orleans District of the Corps of Engineers, Colonel Alvin Lee, issued a formal apology. "Please accept my apology for the unprofessional comments someone in my District posted to your web site", said the letter. "I have reinforced with my entire staff that this was an inappropriate and unacceptable use of our computers and time". [33] On 23 June 2009, US Senator Mary Landrieu ordered a Pentagon investigation into the issue. [34]

On 29 September 2009, the Department of Defense Inspector General's Office closed its investigation. "We believe that (corps New Orleans District office) officials took appropriate actions once informed of the allegations at issue," Assistant Inspector General John Crane said in a letter to U.S. Sen. Mary Landrieu, D-La. "Accordingly, further review by this agency is not warranted." Those actions included strongly worded messages to corps employees telling them comments that demeaned corps critics were not allowed. In addition, access to the site of the Levees.org group was blocked from corps computers, preventing employees from commenting there. Lastly, the employee of a contractor—who was a former corps employee himself and was identified as using a government computer to post disparaging remarks on NOLA.com—was barred from working on corps projects. [35]

Public Relations Controversy

In 2007, the New Orleans District hired a PR firm, Outreach Process Partners (OPP), allegedly to develop educational materials and set up public meetings that the Corps is required by law to hold in order to get feedback from residents about corps' projects. [36] For this work, OPP received nearly $5 million. [37] The total cost of the PR contract is $5,250,000. [38]

In May 2009, an internet blogger discovered that OPP had a bar graph on its website that boasted how it helped reduce negative news coverage that plagued the Corps following Hurricane Katrina. [39] The group Levees.org publicly stated that corps' should not be spending taxpayer dollars trying to repair its reputation. [40]

Water supply issues

Army involvement in works "of a civil nature," including water resources, goes back almost to the origins of the U.S. Over the years, as the Nation's needs have changed, so have the Army's Civil Works missions. Water resources controlled by the Corps of Engineers are used for navigation, hydroelectric power generation, and recreation as well as water supply. The Corps first got involved in water supply in the 1850s, when they built the Washington DC aqueduct. Today USACE reservoirs supply water to nearly 10 million people in 115 cities. In the drier parts of the Nation, water from Corps' reservoirs is also used for agriculture.

Georgia, Alabama, and Florida have been wrangling over how to allocate water from the Chattahoochee watershed for years as metro Atlanta's population has doubled since 1980. In October 2007, the governor of Georgia, Sonny Perdue, indicating an impending crisis with the water supply from Lake Lanier, declared a state of emergency and confirmed that the state would sue the US Army Corps of Engineers who administers the water supply for Atlanta. [41] The Corps acknowledged that they made a mistake in 2006 when they relied on a faulty gauge to measure Lake Lanier's level by nearly two feet. This mistake led to an overestimation of the amount of water left in the lake and the Corps accidentally released about 22 billion US gallons (83,000,000 m3) of water: enough to supply metro Atlanta's needs for about a month and a half. [42]

However, USACE's analysis of the situation differed from the Governor's, indicating that even without rain for nine months, water supplies would still be adequate. The corps sent a letter to Perdue assessing the situation and pointing out that they are "not going to run out [of water] any time soon," [43] In mid-November 2007, the Corps made adjustments to its water retention policies to keep more water in the Chattahoochee watershed. The U.S. Fish and Wildlife Service expedited its study of an interim drought plan submitted two weeks ago by the U.S. Army Corps of Engineers, and concluded that freshwater mussels and sturgeon in Florida and Alabama—kept alive by water from Georgia's Chattahoochee watershed under federal law—will not be jeopardized under the plan. [44] The governors of the three states indicated that they would continue to meet and negotiate. [45]

Other states [46] and tribal nations [47] have also been involved with or had concerns about how the Corps manages water supply, [48] [49] to the extent that Congress [50] or the courts [51] [52] have often gotten involved in trying to mediate disputes.

Wetlands jurisdiction

One of the major responsibilities of the Corps of Engineers is administering the wetlands permitting program under Section 404 of the Federal Water Pollution Control Act of 1972. (also known as "The Clean Water Act"). This Act authorized the Secretary of the Army to issue permits for the discharge of dredged and fill material.

Section 10 of the Rivers and Harbors Act of 1899 (codified in Chapter 33, Section 403 of the United States Code) gave the Corps authority over navigable waters of the United States. As navigable waters are defined as "navigable waters of the United States are those waters that are subject to the ebb and flow of the tide and/or are presently being used, or have been used in the past, or may be susceptible for use to transport interstate or foreign commerce", the Corps has broad authority to enforce this, including licensing of bridges over navigable waters, and the maintenance of pierhead and bulkhead lines.

There is some disagreement over the extent of the Corps' reach into the wetlands, whether USACE or the US Environmental Protection Agency (EPA) should have jurisdiction, and how the wetlands should be regulated.[ citation needed ] Often, it is difficult to describe the problem or make jurisdictional determinations. Many times, people are frustrated because the process isn't transparent or easy. In some cases, it appears that Corps (and EPA) regulators are searching for excuses to justify decisions in allegedly difficult circumstances. [53]

The US Supreme Court has addressed environmental regulation by the Corps of Engineers three times in the last two decades. In 1985, the Supreme Court ruled 9–0 that the Clean Water Act extended to wetlands adjacent to open waters. They left open the question about wetlands not adjacent to Federal waters (United States v. Riverside Bayview Homes, Inc., 474 U.S. 121 (1985)) (see Bayview Homes in Regulatory takings). In 2001, the Court further decided 5–4 that the CWA does not cover areas that had filled with water (Solid Waste Agency of Northern Cook Cty. v. Army Corps of Engineers, 531 U.S. 159 (2001)). The Corps of Engineers had claimed authority over the site by saying that migratory birds used the pond as habitat but were overruled by the Supreme Court because they were claiming powers not granted by Congress by attempting to extend its jurisdiction to ponds with no connection to navigable waters.

The Court's most recent ruling was in June 2006 in Rapanos v. United States . At issue was the way the Federal government regulates the nation's wetlands under the Clean Water Act. The law has been contentious with property owners because it requires a permit for filling and dredging wetlands that empty into navigable waters and their tributaries. Developers have long challenged the Corps' right to regulate wetlands that are not free-flowing into navigable waters. Narrowly avoiding gutting of the Clean Water Act, the Supreme Court voted 5–4 to send the case back to the lower courts for a ruling.

Chief Justice John Roberts wrote, "It is unfortunate that no opinion commands a majority of the court on precisely how to read Congress' limits on the reach of the Clean Water Act. Lower courts and regulated entities will now have to feel their way on a case-by-case basis."

Wetlands jurisdiction by the Corps of Engineers will, for the foreseeable future, remain contentious.

Beach renourishment

The beach nourishment work by the Corps of Engineers is another area of controversy since the temporary replenishment of beach sand is extremely expensive and profitable. The reasons for beach nourishment are often misunderstood. USACE beach nourishment projects are authorized under Section 111 of the 1968 Rivers and Harbors Act (P.L. 90-483 as amended by Sec 940, WRDA '86(P.L. 99-662)) as mitigation for the damage caused by Federal navigation projects interrupting the littoral flow of beach material along shorelines. These laws require that authorized project be cost-shared; and the Federal share of costs for any one project may not exceed $2 million. Many people believe that it is only done for the benefit of well-heeled adjacent land-owners rather than for erosive or littoral purposes. One lobbying firm, Marlowe & Company, charges 40 clients $40,000 each just to lobby for continued support for this controversial effort to save beaches. [54] Many homeowners are disgruntled with the huge annual costs associated with this temporary fix; typical fees are $2,000 per month for a 3 bedroom beachfront condominium (such fees are most probably locally authorized since the Corps of Engineers does not assess fees because of the nature of its Congressionally approved funding). However, many coastal residents are not willing to pay the price. For example, in 2001, the Corps authorized a proposal for a $94 million project 14 miles (23 km) long in Nags Head, N.C. In an attempt to fund the local share of the project, local county commissioners passed a 1 percent sales tax; voters rejected it. Nags Head officials proposed a cheaper, locally funded plan. Again, voters rejected it. "Why," asked WCU program director Rob Young, "should federal taxpayers bail out a beachfront when local residents won't?"[ citation needed ]

Barrier Islands in Louisiana and the Deepwater Horizon oil spill

Reacting to the Deepwater Horizon oil spill, on 23 May 2010, Louisiana Attorney General Buddy Caldwell wrote a letter to Lieutenant General Robert L. Van Antwerp of the US Army Corps of Engineers, [55] stating that Louisiana has the right to dredge sand to build barrier islands to keep the oil spill from its wetlands without the approval of the Corps, as the 10th Amendment to the Constitution does not grant the federal government the authority to deny a state the right to act in an emergency. [56] [57] He also wrote that if the Corps "persists in its illegal and ill-advised efforts" to prevent the state from building the barriers that he would advise Louisiana Governor Bobby Jindall to proceed with the plans and challenge the Corps in court. [58]

New Jersey Beach Project 2017

Despite court actions and an election where Margate NJ voters rejected a planned beach replenishment project, in the summer of 2017, Corps engineers began work creating dunes in Ventnor and Margate City, New Jersey. They made a very big mess, and additionally, beaches which are tested weekly in the summer for bacteria and toxins experienced unprecedented closings due to dangerous levels. [59] [60]

On 2 Aug 2017, Margate Commissioners voted to go back to court in order to seek an injunction. They wanted an immediate work stoppage by the NJ DEP and Army Corps of Engineers. Mistakes in building the dunes caused substantial flooding and contaminated, standing water between the new dune and the bulkheads.

Calls for Corps reform

Some in Congress feel that reforms are necessary in the way the Corps operates. The Corps has been criticized as being mismanaged and lacking oversight and accountability, especially since Hurricane Katrina and the failure of the Army Corps built levees in New Orleans.

Senator Russ Feingold and Senator John McCain pushed to establish two amendments; one an independent review of Corps projects from planning and design to construction, and a second that would require that Corps projects be ranked in importance based on national priorities. In 2006, they succeeded in adding the peer review of corps projects to the Water resources development bill that was working its way through Congress. [7]

In August 2007, Senator Feingold himself tried to block passage of the bill because he felt the reforms it contained would not do enough to change the way the Corps does business.

After a decade of government and independent reports calling for reforming the corps and pointing out stunning flaws in corps projects and project studies, and after the tragic failures of New Orleans levees during Hurricane Katrina, the American people deserve meaningful reform. How many more flawed projects or wasted dollars will it take before we say enough is enough?

— Senator Feingold from the Senate Floor [61]

Calls for reform go back decades; the Corps' credibility had been challenged as early as the late 1920s. Herbert Hoover, then Secretary of Commerce, declared the Great Mississippi Flood of 1927 as "greatest disaster of peace times in our history", which covered 26,000 square miles (67,000 km2) in seven states. More than 700,000 people were driven from their homes. [62] More recent attempts at reform have been made in the 106th, 107th, 108th, and 109th Congresses. [10] But as Senator Feingold indicated by quoting the Times-Picayune: [10]

"Unfortunately, not everyone in Congress is interested in changing the way the corps does business. The McCain-Feingold amendments face opposition and a rival set of measures by the main authors of the water resources bill, Sens. James Inhofe and Kit Bond.... Sham reform won't do anything to restore confidence in the corps, and Congress must do better."

On 8 November 2007, the Water Resources Development Act of 2007 became law over President Bush' veto of the bill.

In 2012, President Obama issued Executive Order 13604, Improving Performance of Federal Permitting and Review of Infrastructure Projects, to streamline and reduce the time required for review and permitting of infrastructure projects. [63] The feasibility study and environmental assessment for the deepening of Charleston Harbor was the first project to be completed under this new process. [64]

The United States Army Corps of Engineers (USACE) is an engineer formation of the United States Army that has three primary mission areas: Engineer Regiment, military construction, and civil works. The day-to-day activities of the three mission areas are administered by a lieutenant general known as the commanding general/chief of engineers. The chief of engineers commands the Engineer Regiment, comprising combat engineer, rescue, construction, dive, and other specialty units, and answers directly to the Chief of Staff of the Army. Combat engineers, sometimes called sappers, form an integral part of the Army's combined arms team and are found in all Army service components: Regular Army, National Guard, and Army Reserve. Their duties are to breach obstacles; construct fighting positions, fixed/floating bridges, and obstacles and defensive positions; place and detonate explosives; conduct route clearance operations; emplace and detect landmines; and fight as provisional infantry when required. For the military construction mission, the commanding general is directed and supervised by the Assistant Secretary of the Army for installations, environment, and energy, whom the President appoints and the Senate confirms. Military construction relates to construction on military bases and worldwide installations.

Hurricane Katrina was a destructive Category 5 Atlantic hurricane that caused 1,392 fatalities and between $97.4 billion to $145.5 billion in damage in late August 2005, especially in the city of New Orleans and the surrounding areas. It was at the time the costliest tropical cyclone on record and is now tied with 2017's Hurricane Harvey. The storm was the twelfth tropical cyclone, the fifth hurricane, and the third major hurricane of the 2005 Atlantic hurricane season, as well as the fourth-most intense Atlantic hurricane on record to make landfall in the contiguous United States.

As the center of Hurricane Katrina passed southeast of New Orleans on August 29, 2005, winds downtown were in the Category 1 range with frequent intense gusts. The storm surge caused approximately 23 breaches in the drainage canal and navigational canal levees and flood walls. As mandated in the Flood Control Act of 1965, responsibility for the design and construction of the city's levees belongs to the United States Army Corps of Engineers and responsibility for their maintenance belongs to the Orleans Levee Board. The failures of levees and flood walls during Katrina are considered by experts to be the worst engineering disaster in the history of the United States. By August 31, 2005, 80% of New Orleans was flooded, with some parts under 15 feet (4.6 m) of water. The famous French Quarter and Garden District escaped flooding because those areas are above sea level. The major breaches included the 17th Street Canal levee, the Industrial Canal levee, and the London Avenue Canal flood wall. These breaches caused the majority of the flooding, according to a June 2007 report by the American Society of Civil Engineers. The flood disaster halted oil production and refining which increased oil prices worldwide.

Prior to Hurricane Betsy in 1965, the OLB developed land and sold it to raise money to build and improve flood protection levees. After Betsy, Congress passed the Flood Control Act of 1965 which directed the Army Corps of Engineers to design and build the hurricane flood protection system enveloping New Orleans. Owing to the 1965 legislation, the OLB's duties were now limited to collecting the 30% cost share for project design and construction, and to maintaining and operating completed flood protection structures.

In New Orleans alone, 134,000 housing units — 70% of all occupied units — suffered damage from Hurricane Katrina and the subsequent flooding.

Drainage in New Orleans, Louisiana, has been a major concern since the founding of the city in the early 18th century, remaining an important factor in the history of New Orleans today. The central portion of metropolitan New Orleans is fairly unusual in that it is almost completely surrounded by water: Lake Pontchartrain to the north, Lake Borgne to the east, wetlands to the east and west, and the Mississippi River to the south. Half of the land area between these bodies of water is at or below sea level, and no longer has a natural outlet for flowing surface water. As such, virtually all rainfall occurring within this area must be removed through either evapotranspiration or pumping. Thus, flood threats to metropolitan New Orleans include the Mississippi River, Lake Pontchartrain, canals throughout the city, and natural rainfall. Artificial levees have been built to keep out rising river and lake waters but have had the negative effect of keeping rainfall in, and have failed on numerous occasions.

<span class="mw-page-title-main">Bonnet Carré Spillway</span> Flood control operation in the Lower Mississippi Valley, US

The Bonnet Carré Spillway is a flood control operation in the Lower Mississippi Valley. Located in St. Charles Parish, Louisiana, about 12 miles (19 km) west of New Orleans, it allows floodwaters from the Mississippi River to flow into Lake Pontchartrain and thence into the Gulf of Mexico. The spillway was constructed between 1929 and 1931, following the Great Mississippi Flood of 1927, and has been designated as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers.

The Flood Control Act of 1965, Title II of Pub. L. 89–298, was enacted on October 27, 1965, by the 89th Congress and authorized the United States Army Corps of Engineers to design and construct numerous flood control projects including the Lake Pontchartrain and Vicinity, Louisiana Hurricane Protection Project in the New Orleans region of south Louisiana.

The Flood Control Act of 1928 authorized the U.S. Army Corps of Engineers to design and construct projects for the control of floods on the Mississippi River and its tributaries as well as the Sacramento River in California. It was sponsored by Sen. Wesley L. Jones (R) of Washington and Rep. Frank R. Reid (R) of Illinois, in response to the Great Mississippi Flood of 1927.

The United States Army Corps of Engineers is involved with a wide spectrum of public works projects: environmental protection, water supply, recreation, flood damage and reduction, beach nourishment, homeland security, military construction, and support to other Governmental agencies. In nineteen (19) different Flood Control Acts since 1917, the United States Congress has authorized the corps to design and build flood protection projects and one risk reduction system in the Greater New Orleans area and throughout the nation.

<span class="mw-page-title-main">IHNC Lake Borgne Surge Barrier</span> Bridge in New Orleans, Louisiana

The Inner Harbor Navigation Canal Lake Borgne Surge Barrier is a storm surge barrier constructed near the confluence of and across the Gulf Intracoastal Waterway (GIWW) and the Mississippi River Gulf Outlet (MRGO) near New Orleans. The barrier runs generally north-south from a point just east of Michoud Canal on the north bank of the GIWW and just south of the existing Bayou Bienvenue flood control structure.

<span class="mw-page-title-main">New Orleans Outfall Canals</span>

There are three outfall canals in New Orleans, Louisiana – the 17th Street, Orleans Avenue and London Avenue canals. These canals are a critical element of New Orleans’ flood control system, serving as drainage conduits for much of the city. There are 13 miles (21 km) of levees and floodwalls that line the sides of the canals. The 17th Street Canal is the largest and most important drainage canal and is capable of conveying more water than the Orleans Avenue and London Avenue Canals combined.

<span class="mw-page-title-main">Hurricane & Storm Damage Risk Reduction System</span>

The greater New Orleans Hurricane & Storm Damage Risk Reduction System (HSDRRS) is an infrastructure systems in southern Louisiana which seeks to provide the greater New Orleans area a 100-year level of risk reduction, meaning reduced risk from a storm surge that has a 1% chance of occurring or being exceeded in any given year. In 2019, the Army Corps of Engineers announced that due to increased rate of sea level rise and continued sinking of soil the levee system would no longer offer original planned levels of protection as early as the year 2023.
